Question

Write a real world problem that can be modeled by the equation 1.25=0.75x+50

Answer 1

Timmy's mother gave him $50 to go to the arcade, every time he played a game (x) he lost 75 cents, at the end of the day, after playing 65 games (x = -65), he had $1.25 left over. 
So, $50 + $0.75 (-65) = $1.25
